In the third quarter of 2025, billionaire hedge-fund manager Daniel Loeb’s Third Point Management nearly doubled its stake in Meta Platforms, acquiring an additional 3.2 million shares. This move reflects strong conviction in Meta’s 26% year-over-year revenue growth reported for Q3, driven by expanding ad impressions (+14%) and a 10% rise in ad pricing. Third Point’s intensified exposure suggests confidence in Meta’s AI-enhanced targeting tools and the company’s ability to monetize burgeoning user engagement across Facebook, Instagram and new channels such as Threads and WhatsApp.

During the same quarter, FFG Partners LLC boosted its Meta holding by 28%, adding 2,684 shares to bring its total to 12,266 shares, making Meta its 19th largest position. Conversely, Westend Capital Management trimmed its Meta stake by 16.3%, selling 4,664 shares to end Q3 with 24,035 shares. Meanwhile, Marathon Asset Management reduced its position by 23.6%, offloading 32,120 shares. These contrasting moves underscore a debate among institutions: while some view Meta’s forward P/E near 22 as attractive—below its five-year average—others are locking in profits ahead of increased capex on AI and data-center expansions.

Meta’s senior executives have been net sellers over the past three months, disposing of more than 42,000 shares collectively. CTO Andrew Bosworth and CFO Susan J. Li each reduced their holdings by over 7% and 5%, respectively, signaling potential caution about near-term stock performance or portfolio diversification. Insider sales totaling nearly $27 million represent 13.6% of outstanding insider ownership, a level that typically warrants close monitoring by investors concerned about executive sentiment on valuation and growth trajectories.

Meta continues to ramp up AI-related expenditures, recently completing a $2 billion acquisition of a startup specializing in generative-AI agents and committing $15 billion for a minority stake in an AI-training platform. These strategic deals bolster Meta’s access to proprietary algorithms and expand its footprint in high-margin AI services. With R&D spending projected to grow by 35% in fiscal 2026 and management targeting a return on incremental AI investments above 25%, investors should weigh near-term profit pressure against the potential for outsized earnings acceleration once AI-driven ad personalization and metaverse initiatives reach scale.
